Author's Note: There will be some changes to the One Punch Man story, like how there is no Saitama or Blast in this story.

Secondly, Izuku will be very OP in this story. Not Saitama OP, for he can still get injured, but as the Number One Hero who is stronger than Darkshine, Bang, and even Tatsumaki, it will take a LOT to hurt him.

If you have any questions, PM me because I do not read reviews. I'm sure you can all guess why.

Enjoy.

( City A )

For the residents of City A, the day started nice and peaceful as the children were dropped off at school while their parents headed off to work.

All seemed right with the world, until a massive explosion suddenly erupted in the middle of the city, destroying buildings and killing thousands of people in a split second. People from miles away stumbled or fell as the shockwave from the explosion hit everything in the surrounding area, shaking nearby buildings and shattering windows.

Once the explosion subsided, a massive crater was all that was left of what used to be a residential area in City A. Standing in the centre of the crater was the source of the explosion which so happened to be a Mysterious Being who was a large, purple hairless humanoid with two rounded antennas on its head and had a muscular body.

The Mysterious Being took in his surroundings in disgust before he flew up into the air in a great burst of speed. Once high in the air, the Mysterious Being conjured up four orbs of pure energy before launching them throughout the city, destroying even more buildings and killing all who reside in them.

( Hero Association HQ - Control Room )

Inside the control room of the Hero Association Headquarters, everyone was trying to contain the situation when a nearby explosion caused by the Mysterious Being made the building shake.

"It's closing in!" shouted a console operator.

Another operator turned away from his blaring console, looking for answers. "Damn, so who's available!?"

"We have confirmation that Lightning Max and Smile Man are on their way" exclaimed a female console operator who inwardly hoped that the two A-Class Heroes could defeat the Mysterious Being.

( City A )

Lightning Max and Smile Man were just two of the thirty-one Heroes who were lying among the pile of rubble, having been effortlessly defeated by the Mysterious Being who continued to wreak havoc across City A uninterrupted.

"M-Mommy! D-Daddy!" cried a little girl, standing on her lonesome in the middle of the ruins that once made up a part of City A. So distracted in her grief of losing both her parents that the little girl didn't notice the Mysterious Being walking towards her from behind.

The Mysterious Being studied the crying little girl for a moment before he stretched out his rapidly bulging arm with the intent to squish the girl like a grape. With an evil chuckle, the Mysterious Being clenched his enormous hand around the little girl but was bewildered when he didn't feel the human girl's bones snap or see her blood squirt out. The Mysterious Being opens his hand and to his surprise, he doesn't see any sign of the little girl, dead or alive. Sensing something, the Mysterious Being glanced to his right and saw the still-living little girl with another human who had somehow managed to grab the girl and take her away in the split second that it took him to clench his fist.

"You're a fast one" stated the Mysterious Being who was aware that the human moved so fast that he didn't see them. "Who are you?"

The little girl stopped crying as she stared up at the Hero with tearful eyes wide in shock and awe. "I-It's you."

The Hero smiled down at the little girl who he gently lowered to the floor. "Don't you fear..." The Hero stood up to his full height of 7'4" and turned to face the Mysterious Being, showcasing his costume which was made up of a full-body green jumpsuit that stretched along his muscular build, a red belt, beige gloves which covered the full-length of his arms, red boots, knee pads that extended down his legs and a diamond-shaped respirator which hung by his neck. The man himself had a short mess of dark green curly hair that stuck at odd angles around his head, green eyes, and a set of four symmetrical freckles in diamond formations with one on each cheek. His cheeks have lost much of their roundness, having somewhat sharpened over the years. Unique in appearance, but it didn't turn away from his attractiveness.

"... for Deku is here!" declared Izuku Midoriya or rather, the S-Class Rank 1 Hero, Deku.

The Mysterious Being simply looked down at the Hero in annoyance. "Deku? As in useless? You're kidding" asked the Mysterious Being in doubt. "What kind of half-ass name is that? Mine is far superior for I am Vaccine Man!" declared the Mysterious Being who passionately slapped his chest. "The earth is a single living organism. You filthy humans are nothing but a disease-causing bacteria, eating away at her precious life force" exclaimed Vaccine Man with self-assured passion. At the same time, the Mysterious Being began to transform as his muscles bulged, spikes grew all along his body, and two long, but sharp tusks stretched out from his jaw.

"Why do they always feel the need to tell me all about their back story?" wondered the smiling Hero, Izuku Midoriya, who watched on as Vaccine Man quickly grew taller until he got to the point where the Mysterious Being was now a towering monster of muscle, spikes and razor-sharp claws.

"In order to wipe out humanity and the evil civilization built on her surface, the earth in her infinite wisdom has given birth to me!" declared Vaccine Man who finally transformed into his True Form. "And I shall begin my purge of humanity by killing you!" roared the transformed Mysterious Being who lunged at Deku with the intent to rip him apart.

Unfortunately for Vaccine Man, he failed to grasp the fact that he wasn't facing off against any Hero like the ones he already defeated. No, he was facing off against the Number One Hero in the entire world!

"If not for you causing so much death and destruction yourself, you might have had a point."

Faster than the Mysterious Being could grasp, Deku disappeared in what appeared to be a bolt of green lightning and appeared beneath Vaccine Man who had yet to realize his impending death.

Izuku reared his right arm back which was crackling with emerald green energy that resembled lightning, a result generated whenever he used the power of his Quirk, One For All.

"Full Cowl: Spark Punch."

In the tenth of a second, Deku uppercuts Vaccine Man with more than enough power to rip the head off of the Mysterious Being. To the little girl who watched the Number One Hero defeat the Mysterious Being with practical ease, it looked like Deku just killed the monster with an actual punch made up of green lightning.

Vaccine Man's large monstrous head was launched up into the air faster than a speeding bullet and disappeared from view, having flown higher than the human eye could naturally see. Even more spectacular was that Deku's punch didn't just kill the powerful monster, but the power unleashed from his fist dispersed the rising smoke and clouds that filled the sky, leaving nothing behind but clear blue skies for all of City A to enjoy.

The little girl's eyes sparkled in awe as she watched the Number One Hero, Deku, turn towards her with the same caring smile he was famously known for. The sunlight that shined down on the Hero only made him look more angelic in her eyes.

So distracted in her awe, the little girl didn't notice or care when the headless corpse of Vaccine Man fell over with a loud thud.

( Hero Association HQ - Control Room )

"We can't thank you enough for your help, Deku. We would have been in big trouble if not for you" thanked Bearded Worker, bowing his head in respect for the Number One Hero. Even after defeating the Dragon-level monster, Deku went out of his way to bring back the thirty-one injured Heroes and any civilians who were injured during Vaccine Man's rampage. They were all quickly transferred to the infirmary so they could be treated by the best doctors available. "Most of the other S-Class Heroes would have just left after defeating the Mysterious Being."

Despite being twenty-five years old and officially classed as the Strongest Hero, Izuku Midoriya could still get a bit bashful when given praise. "It was nothing. Just doing my duty, that's all" answered Midoriya who waved off Bearded Worker's praise with an embarrassed chuckle.

The smiling Bearded Worker raised his head, elated that they have someone like Deku to protect them from global threats. "Still, you have our gratitude." His colleagues all showed their agreement by happily nodding or verbally praising Deku.

Izuku chuckled with an embarrassed blush. "I guess I have no other choice but to say you are all welcome. Now then, if that's all, I best get going. The cities won't patrol themselves" he said and with a wave, the Hero walked out of the control room to continue his patrol.

As he strolled down the hallway while politely greeting the Hero Association employees who all showed their gratitude to him, Izuku felt like reminiscing about the life he had made for himself. "To think that this is my life now."

Ten years ago, he had been nothing more than a Quirkless loser who fantasized about becoming a Hero like every other kid. Now, he was the Number One ranked Hero in the entire world, having held the title ever since the Hero Association established itself three years ago. For the seven years before that, he had been fighting criminals and Mysterious Beings as a vigilante.

Back in his original world, vigilantism was considered a serious offence. At first, he had been worried about being potentially named a criminal by the world governments for performing his vigilante acts, not that it would've stopped him from going out and saving people. Imagine his surprise when he found out that not only was he not getting in trouble for his vigilantism, but the government was encouraging him to continue. Being able to fight toe-to-toe with monsters was probably what convinced the politicians to look the other way. In the past fifteen years, the frequency of Mysterious Being appearances had increased with some being much more dangerous than others, which would explain why vigilantism was encouraged. There was only so much the police and military could do against monsters that could withstand gunfire and crush tanks with their bare hands, so Izuku and others who could defeat monsters on their own were welcomed to do so by the world governments.

A couple of years later, Izuku's dream came true once he officially became the Number One ranked Hero in the entire world, just like All Might. "I only wish All Might and mother could see this" he thought, missing the two most important people in his life, especially his mother. Ten years was too long to be without the woman who single-handedly raised him.

Stepping out of the Hero Association Headquarters, Izuku looked up at the clear blue skies and blocked the sunlight from hitting his eyes. Reminiscing made him remember how he ended up in this world in the first place.

( Ten Years Ago - USJ )

Izuku Midoriya couldn't believe they all managed to survive an actual attack from Villains.

Class 1-A's trip to the USJ facility was intended to be used as an example for a training exercise on how they would save civilians during different kinds of natural disasters, like landslides, fires, and floods. Instead, the whole trip had become far scarier and more dangerous than anyone could have predicted.

Villains attacked the USJ facility intending to kill the Symbol of Peace, All Might. Unfortunately for everyone involved, All Might didn't make it to the class on time like he was supposed to. With their main objective unavailable, the Villains then turned their aggression onto the class of first-year Hero students. There were only two Pro Heroes to fight the Villains and while Eraserhead did a good job in taking out many of the small-time Villains, he was eventually beaten by the Villain who had severed hands all over his body, and the giant monster with the exposed brain. Thirteen was also defeated by a Villain who had a Warp Quirk, which left the first-year students to fend for themselves.

All of Class 1-A battled Villains all across the USJ facility, but before anyone could be severely hurt, All Might showed up just in time. What small-time Villains that remained were quickly taken out by All Might. Witnessing the Symbol of Peace defeat the Villains in so little time filled the students of Class 1-A with hope at a time that it was badly needed.

That hope wavered when All Might battled against the monster that the leader called a Nomu. To the shock of those who witnessed the fight, the Nomu could not only keep up with All Might, but it could hurt him as well. The leader of the Villains explained that Nomu possessed multiple Quirks, as hard as it was to believe, including a Shock Absorption Quirk which nullified all the damage done by All Might's punches.

All seemed lost until All Might showed them what it was like to go Plus Ultra and went beyond his limit. In a clash between titans, All Might came out victorious after he launched Nomu out through the ceiling of the facility with one powerful Smash. As expected by the number one Hero, All Might was victorious, but he didn't come out unscathed. The tough fight had left All Might weak, which wasn't missed by the Villain leader. The Villain tried to attack the weakened Symbol of Peace, but Izuku moved to stop him and nearly got himself killed in retaliation. Thankfully, the rest of the teachers arrived just in the nick of time. Before the Villain leader could kill him, Snipe managed to shoot him several times, forcing the injured leader to teleport away with the Warp Quirk Villain.

With the Nomu and the Villains finally defeated, Izuku dropped down to his knees and let out a breath of air in relief. The successor of All Might could never have predicted that he would nearly die so early in his Hero career, especially not while he was still just a first-year student. That was the unpredictable Hero's life for you.

"F-Fucking brats!"

Izuku turned towards the source of the voice and widened his eyes when he saw that one of the unconscious Villains had woken up. The shirtless Villain was lithe when compared to the rest of his comrades and from the way he was supporting his bruised right arm, he appeared to be injured, likely caused by Eraserhead during his beatdown on the small-time criminals. That was good, it meant Izuku could probably apprehend the criminal on his own without resorting to hurting himself by using One For All. Just as Izuku was about to take on the criminal, he stepped back when he saw the man aim his hand toward Midoriya who noticed how the limb glowed a sinister shade of red. The 1-A student didn't know what the Villain's Quirk was so he kept his distance just in case.

"Die you little shits!" roared the Villain before he fired a red beam of energy from his uninjured hand, but not at Midoriya. With the Villain weak and injured, his aim faltered so instead of firing his energy beam at Midoriya, it instead flew towards the back of an unsuspected Tsuya Asui who was too busy celebrating their victory to notice the beam of energy heading towards her.

Again, Izuku's feet were moving on their own without needing to think, just like he did when he tried to save Kaachan from the Sludge Villain. All he knew was that Tsuya was in danger and he was the only one there to save her.

"Midoriya?" asked Tsuya, turning towards Izuku who she saw was running towards her in what looked like a panic. She didn't get an answer for Izuku roughly shoved her away. "What are yo-" Tsuya started before her eyes widened in horror when she saw a red energy beam hit her classmate, exactly where she was just standing. She realized that if Midoriya hadn't shoved her aside. she would've been hit instead. "R-Ribbit?" she croaked out, watching in horror as the light from the Villain's Quirk washed over Midoriya's body which then started to break down into particles of light that quickly faded away, starting with his legs.

You'd think that after ten years of bullies severely beating him and breaking his limbs whenever he used his Quirk, Izuku would be used to pain by now. Sadly, the pain from being hit with whatever the Villain's Quirk was made all those past experiences feel like puppy kisses in comparison. It was like every cell in his body was being pierced by a sharp needle at the same time.

Yet, seeing Tsuya looking up at him from the floor, alive and well was enough to make the pain worth it. He might not get to grow up and become the Hero he always wanted to be, but knowing that he managed to save at least one person was enough for him to die in peace. He just wished he could've said goodbye to everyone first.

And so as he accepted his faith, Izuku Midoriya closed his eyes one last time and allowed himself to succumb to darkness as the last piece of his existence faded away into particles of light.

xXx

Much to Izuku's surprise and great relief, he didn't die that day. Instead, he had been seemingly transported to an alternate world, so much like his own, and yet so different. Izuku pondered if the Villain responsible for his conundrum understood what his odd Quirk could do, doubtful as it may be. The Villain probably thought that it just disintegrated anything he used it on.

In the end, Izuku survived, but with no way to return home, he had to make do with the one he found himself in. A world that was both familiar and incredibly strange.

Instead of countries, this earth had just one large land mass which was filled and separated with gigantic cities which were named after the letters of the alphabet. Not the most creative, but it did keep things simple. However, the most shocking difference between his world and this one was that humanity hadn't evolved to the point of having Quirks. Where his home world only had a Quirkless population of 20%, this world was 100% Quirkless, a fact that both baffled and amazed the once Quirkless man.

While there may be such large differences between the two earths, there were still some similarities that couldn't change, alternate world or not, such as criminals that could be found in every city. Yet, criminals were considered nothing more than nuisances when compared to the real threat.

Monsters. They were also known as Mysterious Beings, seeing as how humanity still had no clue on how they first came to be. What they did manage to learn was that some species of monsters have lived unnoticed on earth for millennia, but the most common kind of monsters were those who were once human but abnormal cell reactions would transform them into monsters either because of a bad habit or a burst of dissatisfaction. It reminded Izuku a lot about Quirks, but these transformations could occur at any time and always result in the person turning bloodthirsty. These Mysterious Beings varied in strength, either weak enough to barely be a threat to a group of civilians or powerful enough to threaten the safety of multiple cities, such as Vaccine Man.

The first couple of years that he spent in this strange world were spent moving from city to city, learning to better control his Quirk, One For All. Since he didn't have access to Recovery Girl or any suitable ID, he had no choice but to resort to using One For All sparingly until he could better control the Quirk's immense power without having to break his limbs.

Thankfully, trying to use One For All sparingly led to him creating Full Cowl, a technique that allowed him to spread the flow of power from One For All all over his body instead of focusing it all on one part of his body like he usually did. At first, he had only been able to implement 5% of his Quirk's total power without damaging his body, but after two years of training and fighting both Villains and Mysterious Beings, he learned to master One For All to its fullest.

For seven years, Izuku spent much of his time fighting Villains and Mysterious Beings as a vigilante, since neither the police nor the military could fight against monsters that were Demon-level threats or higher. However, his time spent as a vigilante changed three years ago after he saved the grandson of the multimillionaire, Agoni, from a Mysterious Being who went by the name Crablante. Agoni was so moved by the heroic act that he used his wealth and connections to create the Hero Association and the National Superhero Registry, therefore creating an organization that could directly fight against the threat of Mysterious Beings.

Izuku was the first to join the Hero Association and did so under the Hero name, Deku. The next three years were spent defeating dangerous criminals and monsters of all different shapes and sizes. It didn't take him long for him to rise in the rankings until he eventually became the Number One Hero in the world. After a lifetime of others telling him that he couldn't be a Hero, Izuku was brought to tears during the official ceremony, having finally made his dream a reality.

Shaking himself out of his head, Deku bent his knees and with a mighty leap, he went into the air, flying over the high-rise skyscrapers of City A.

Another surprising factor that Izuku eventually learned about One For All was that the Quirk carried the vestiges of its previous wielders. As well as that, all their Quirk factors had merged with One For All's core, providing Izuku with the Quirks of all his predecessors. Not including One For All, he now had access to six other Quirks. One such Quirk was Float which belonged to All Might's predecessor and mentor, Nana Shimura. He was currently using said Quirk to help him fly through the sky like a green comet.

Deku stopped in midair when suddenly and without warning, an explosion erupted a few miles in the direction of City D. At the centre of the explosion stood one of the largest Mysterious Beings Deku had ever seen. The Mysterious Being resembled a man without skin and had bone-like armour covering parts of his body. Since the monster didn't have any skin, Izuku could see its revealed muscles and tendons. The Mysterious Being was so tall that it stood well above the clouds and blocked out the sun for millions of people in City D. Giving a quick calculation, Izuku estimated the monster to be nearly 300 meters in height.

Emerald lightning enveloped Deku's form before he disappeared in a burst of speed.

Standing atop the shoulder of his transformed brother, Fukegao laughed as he watched Marugori stomp on hundreds of people who were unlucky enough to be in the giant's path. "Yes! This is incredible little brother! I never thought it would work so well" laughed the mad scientist. After years of working on his Biceps Brachii King steroid, he had given the drug to his little brother, Marugori, who craved power so he could surpass Deku as the strongest man in the world. The result was Marugori turning into a mutated giant who stood taller than any building or mountain and was stronger than any Hero.

"With my brains and your brawn, by combining the greatest of minds and the strongest of bodies this world has to offer, the two of us will conquer the earth and rule together as kings. We're unstoppable!" declared the scientist with a mad laugh.

Marugori reeled his gigantic right arm back to blow away the nearby city, but the giant was cut off when a blur of green collided with his elbow. The resulting impact shattered the giant's elbow, causing it to bend unnaturally.

Fukegao grabbed onto his screaming brother's shoulder to steady himself from all the sudden shaking. "Marugori?! What happened?!"

"So are you the one who started all this?"

Fukegao looked towards the source of the voice and paled at the sight of the green-haired man who was casually standing in the middle of the air as if it were normal. It didn't make logical sense, but then again, nothing about Deku made any logical sense. "Marugori, it's Deku! Kill him before he can stop us!"

While still in pain from having his right arm broken, Marugori complied with his older brother's order. The giant pulled back his uninjured arm and threw a punch at blinding speeds, far faster than a creature of his size should be capable of making.

Still, even at such speeds, Deku's eyes easily kept track of the monster's attack. He could've dodged the attack without issue, but he didn't for it wasn't necessary. Deku stayed hovering in the air as the massive fist flew at him. Just before the attack would connect, Deku held out his right hand and caught the punch, resulting in a powerful shockwave that could be felt for miles. Yet, Deku didn't so much as budge an inch, to the disbelief of the brothers.

"How about we all go for a fly?" Deku clamped his hand on the monster's fist and suddenly bolted upwards. With his fist caught in the Hero's unyielding death grip, Marugori was taken along for the ride and with him, Fukegao.

"B-Brother, do something!" yelled a terrified Fukegao who was barely holding onto the shoulder of his younger brother. Despite his transformed brother weighing well over one hundred tons, Deku didn't seem to have a problem lifting him into the sky. In fact, it almost seemed like they were going faster by the second.

"I-I'm trying!" yelled Marugori who couldn't take his hand back from the Hero. The Hero's pull was too strong and his other arm was dangling by his side, broken.

Normally, Deku would flatten the Mysterious Being and be on his way, but seeing as how this Mysterious Being was nearly 900 feet tall, he couldn't just recklessly kill it. If he did, the monster's massive corpse would collapse onto City D, killing anyone who wasn't fast enough to evacuate. He couldn't kill it in the ocean either, since its large size would cause the water levels to rise drastically, resulting in floods. So, since he couldn't kill the Mysterious Being anywhere on the planet, there was only one last place he could do it.

"Full Cowl: Seismic Toss!"

After flying nearly fifty kilometres upwards, Deku grabbed the monster's fist with both hands. Gritting his teeth, he tossed the giant over his shoulder and straight out of the stratosphere. Marugori's screams could be heard for a few seconds after he was chucked off the planet but they faded as the giant was lost in the deep expanse of space.

The same couldn't be said for the Fukegao who had fainted from a lack of oxygen and was currently falling back down to earth. If not for Deku flying down and catching him, he would have become a bloody splatter across the ground.

With the unconscious scientist on hand, Deku looked back up at the sky to make sure that the giant wasn't going to be making a return before he flew down towards the closest Hero Association Branch building.

( City Z - Izuku's Apartment )

"Phew, another busy day" sighed Deku once he entered his apartment.

As the Number One Hero, Izuku's fans numbered in the billions and while grateful for all their support, some of them could act a bit extreme at times. Many Heroes have reported incidents when excited fans broke into their homes, which was why most Heroes keep their home addresses a secret nowadays. For that same reason, Izuku had his apartment in City Z which was the least populace of all the cities, due to the high percentage of monster appearances in the area, specifically in the Ghost Town. The apartment also happened to be on the outskirts of the Ghost Town so he didn't have to go far whenever he got word of a monster sighting in the area.

Midoriya's apartment was quite large for a person who lived alone as it included a large sitting room, two bedrooms, two bathrooms, and a large kitchen that also made up as a dining room.

Since he lived alone, Izuku was caught off guard when he smelled something cooking in his apartment. Following the lovely scent to the kitchen, all the while, keeping himself prepared for a possible fight with an intruder, Izuku slowly opened the door to the kitchen and found the culprit of the delicious smell of food.

"Welcome home, Izuku" greeted Fubuki who smiled at Midoriya while a stew boiled in a pot on Izuku's stove. "I cooked us dinner."

Fubuki was a young woman with a curvy figure, chin-length, dark green hair styled in a bob, and her eyes were a shade of light green. Her attire consisted of a long white fur coat, a dark green form-fitting dress, thigh-high black boots, and several pearl necklaces.

Izuku calmed down when he saw that it was only Fubuki. He looked around his large kitchen and rolled his eyes at the B-Class Rank 1 Hero. "Last I checked, this is my apartment so forgive me for wondering why people are in it. By the way, don't say you're cooking dinner when you aren't!" exclaimed Deku while pointing an accusing finger at Fubuki who was sitting at the dining table while her subordinates, Eyelashes, Lily, and Mountain Ape cooked up the stew.

"I told you he'd notice," said a panicked Eyelashes to Fubuki who ignored him. The B-Class Rank 2 Hero was currently setting up the table for both Izuku and Fubuki.

"He's going to kill us" muttered a heavily sweating Mountain Ape who was stirring the pot of stew. Mountain Ape was confident in his skills, as well as that of his fellow B-Class Heroes, but they just broke into the apartment of Deku himself! A man who could shatter mountains, split the seas, and clear the skies, all with a single punch. The entirety of the Blizzard Group could attack Deku at the same time while he had his hands tied behind his back and they would still have no hope of defeating the man who stood at the pinnacle of the Hero Association.

Unlike Eyelashes and Mountain Ape, Lily wasn't afraid of breaking into the home of the S-Class Rank 1 Hero as she quickly jumped in front of Deku with stars in her eyes and a notebook in her hands. "Mr. Deku, could I please have the honour of getting your autograph?" she asked, practically pleading.

As much as he should be annoyed at Lily for breaking into his home, Izuku couldn't when the young girl looked up at him with so much hope and adoration in her eyes. Not someone to let a fan down, Izuku took the offered notebook and pen from the young woman before signing his name on one of the pages. "Here you go," he said, offering the notebook back with a smile.

A blushing Lily took her notebook back and looked down at it like as if it were a priceless artefact. "T-Thank you so much, sir!" she thanked, bowing low.

Izuku couldn't help but chuckle over the girl's obvious excitement. "She reminds me of myself when I first met All Might" he thought in amusement, remembering how he had the same look on Lily's face all those years ago when All Might first signed his book. Ten years ago, he was a naïve Quirkless boy who idolized Heroes to an unhealthy degree. Now, he was the Number One Hero who still idolized Heroes to an unhealthy degree. "How times change."

Fubuki used her psychic power to pull back the chair across from her. "Come and have a seat. Dinner should be ready soon."

Having grown used to Fubuki talking to him as if he were her underling, he turned around and made his way to his bedroom. "Let me change out of my costume at least."

"Do you want any help?" asked Fubuki with a coy smile. She giggled when Izuku answered by slamming his bedroom door close. "Ah, Izuku is shy."

"Why do you antagonize him so?" asked Eyelashes who was on the verge of crying. He knew that Fubuki had a crush on Deku, just like every other straight woman, but why did she always feel the need to get under his skin?

Fubuki turned to her subordinate with the same coy smile plastered on her face. "I don't know what you mean."

Mountain Ape placed two plates full of stew onto the table before he and his partners lined up beside one another to bow. "If that will be all, ma'am, we will take our leave."

Fubuki nodded in agreement and waved them off. "You are dismissed for the day."

That's all she had to say before the three subordinates ran out of Deku's apartment faster than Fubuki had ever seen them move before. The leader of the Blizzard Group soon turned her attention to Izuku who walked back into the kitchen, now wearing a sleeveless green t-shirt and black shorts. Not that Fubuki was complaining since the shirt did nothing to hide his powerful muscles, nor did the shorts that showed off a lot of leg to the B-Class Rank 1 Hero. She giggled when she read the word 'T-Shirt' which was displayed in the middle of Izuku's t-shirt in bold black writing. Greatest Hero in the world, but fashionable, Izuku was not.

"Stew smells good" complimented Izuku who took the seat across from Fubuki before he dug in. It was nice not having to cook for himself now and again.

"I hope you enjoy it. I made it with all my heart" stated Fubuki with a gentle smile and a bit of red colouring her cheeks.

"Make sure to tell Mountain Ape that I appreciate the cooking" answered Izuku, although Fubuki either didn't hear him or simply chose to ignore his response. "So I see you broke into my apartment again."

"Breaking in are such dirty words to use in front of a lady like myself" stated Fubuki, waving off his accusation.

"Breaking in sounds like an accurate description of what you did," remarked Izuku, pointing his fork in an accusing manner at Hell's Blizzard. "You can't just enter someone's home without permission."

Just after Izuku said that a green glow enveloped his kitchen window before it telekinetically opened and a small, lithe figure let herself into the apartment.

"Izuku, I came to see if you wanted to have dinn-" S-Class Rank 2 Hero, Tatsumaki, World's Strongest Woman, and older sister to Fubuki stopped when she noticed that Deku and her sister were having dinner together in his apartment. "What is this?" she demanded, folding her arms together while glaring down at the two.

Tatsumaki is a petite woman who has an adolescent face with emerald green eyes, and green hair that naturally curls on the ends. She is adorned in a form-fitting black dress with long sleeves, and four high-cut leg slits that show off her shapely long legs and low-heeled black shoes.

Izuku saw how a few objects in his kitchen began to levitate, all due to Tatsumaki's rising telekinetic power which was fluctuating in response to her rising anger. "Tatsu, calm down! We're just having dinner."

"And if dinner is as good as this, I can't wait for dessert" teased Fubuki, uncaring of the rising pressure of her older sister's power. She knew that Tatsumaki wouldn't hurt her so she was in no real danger of suffering Tatsumaki's rage. The same couldn't be said for the apartment complex which was starting to shake from Tatsumaki's power.

Not wanting to have his apartment collapse on top of him, Izuku slammed his fist down on his dining table, not hard enough to break it but enough so it would produce a loud BANG. "ENOUGH!"

Izuku's authoritative shout snapped Tatsumaki out of her state of anger and she then looked down at the floor in embarrassment, looking more like a child who had been scolded.

"Tatsu, I've told you this before a thousand times, you can't let yourself lose control over your powers when you get angry. The last thing we want is for a whole city to collapse, just because you got emotional" said Izuku, hating how he had to scold Tatsumaki, but if he didn't then nobody else would. The only person in the world that Tatsumaki allowed to talk back to her was himself. Anyone else would usually find themselves a hundred feet underground or tossed into orbit, and that was if she was feeling merciful.

"I'm sorry" muttered Tatsumaki, refusing to look at Izuku's disappointed eyes.

"Apology accepted. Now come down and take a seat while I prepare you some stew" smiled Izuku, standing up to get a plate of stew for his fellow Class S Hero.

"I made it myself" stated Fubuki with a smug grin while a glaring Tatsumaki lowered herself down to the chair beside Izuku's. At least that was one little victory she could rejoice in.

"She had her subordinates make it" revealed Izuku without mercy, causing Fubuki to lose her smug grin and Tatsumaki to smirk in return. "And please stop teasing your sister, Fubuki." Izuku placed the stew in front of Tatsumaki, either not noticing or ignoring the electricity that seemed to spark between the two glaring sisters.

Sitting back down to continue his meal, Izuku recalled how he was introduced to the Psychic Sisters.

Ten years ago, a few weeks after he was transported to this world, Izuku had saved Tatsumaki's life. She was kept captive and experimented on by a group of scientists, having been sold to them by her parents when she was just a child. For years, the scientists had conducted countless experiments on Tatsumaki, many of which were agonizingly painful, all so they could study her powerful Esper abilities. At some point, a Mysterious Being that the scientists had been keeping locked up escaped, killing every scientist in the facility. Once the monster finished with the scientists, it came for her. At the time, Tatsumaki was too afraid to use her powers and would have died, if not for Izuku arriving in time to kill the monster. That was how Izuku and Tatsumaki met, and they've been close ever since.

A few years later, Izuku was introduced to Tatsumaki's younger sister, Fubuki, who was also an Esper, but not as powerful as her older sister. The two were quick to become friends, but Izuku quickly became aware of an underlying tension between the sisters. The source of said tension was Tatsumaki's overprotectiveness over her younger sibling which made Fubuki feel weak and restrained. Izuku managed to convince Tatsumaki to give Fubuki some space to let her grow as her own person. Thankfully, the decision helped to improve the sister's relationship with one another, although they still bickered like siblings often did. They often fought over their views on strength.

Tatsumaki believed that true strength came from oneself, whilst Fubuki believed strength came from working together to defeat one's opponent. Izuku believed they were both right in a sense, not that he could tell them that. Say what you will about the Psychic Sisters but if there was one thing they shared, it was their stubbornness.

"They were talking about you on the news again. They mentioned how you defeated a Dragon-class Mysterious Being in City A after it defeated thirty-one other Heroes who couldn't so much as scratch it. Then you dealt with that giant in City D soon after. Most impressive" said Fubuki, wanting to start a conversation. There was no officially given class for the giant Mysterious Being, but you would have to be blind to not classify it as a Dragon-level threat.

Tatsumaki scoffed. "Of course, Izuku could do what those thirty-one weaklings couldn't. Beating Dragon-level monsters is nothing for someone like him. I bet Izuku didn't even break a sweat!"

Izuku smiled, grateful for Tatsumaki's confidence in him. "It's our job to protect humanity from the threat of those monsters. Any worthwhile Hero wouldn't just stand by and watch as those monsters caused havoc and destruction. I was just doing what was expected of me, simple as that."

"Simple my ass," thought Fubuki, brow twitching in slight annoyance. She loved Izuku's humbleness and down-to-earth attitude, but there were times that he unknowingly bragged without realizing it. Defeating two powerful Dragon-class monsters in one day might be nothing to the S-Class Rank 1 Hero, but for most other Heroes, it was an impossibility. She could have her entire Blizzard Group face off against one of those Dragon-class Mysterious Beings and get wiped out, even with her help. The same couldn't be said for her sister who could've wiped out those two monsters just as easily as Izuku did.

"We should go out on a mission together someday. Y-You know if you wanted to. Not like I care or anything" said Tatsumaki, slowly reverting to her tsundere mode, much to Fubuki's ire. Of all the people her sister had to like, why did it have to be the same man with whom she was hoping to confess her own feelings? She didn't want to compete against her sister for Izuku, but she would if she must and she would win!

Whenever she gathers up the courage to confess her feelings to him anyway.

For now, she'll bide her time and wait for the right moment to strike.
